Innovative energy storage solution for wind farm

ABB has won an order from Dong Energy, the leading Denmark based sustainable energy group, to deliver a 2 MW battery energy storage system (BESS) to support the integration and transmission of power from the Burbo Bank offshore wind farm near Liverpool, UK. The 90 MW Burbo Bank offshore wind farm has been in operation since 2007 and is capable of supplying electricity for up to 80 000 UK homes. This will be the first time an offshore wind farm integrates such a storage system to stabilise the frequency of the grid in UK. The UK’s national grid operates a frequency level of 50 Hz to ensure grid stability and quality of power supplies. Grid frequency is dependent on the balance between power supply and load demand. Integration of large amounts of variable wind energy increases complexity from a supply perspective and can result in frequency variations that can affect grid supply and impact consumers.
